hopper andsluiceway :torY handling ashes,

the nozzles being joined together into a unitary structure adapted to be given oscillatory movement by a single simple connection to direct water progressivelyagainst a pile of ashes on a feed plate and more or less paralf lel to the top surtaceof the latter. u

In the present illustrative Vembodiment I disclose my invention applied in such a manner that the principal elements of the hydraulic system can be made of standard pipe fittings and other simple standard stock, al-A though it is to be understood that the scope of my invention is not limited to the formsYV herein shown and described. 1

A preferred form which I have selected for illustrative purposes is shown inthe drawings herewith, wherein Fig. 1 is a Vertical longitudinal central` section through a hopper and sluiceway in which my invention is embodied;

Fig. 2 is a vertical transversesection taken as indicated by the line 2-2, Fig. 1, looking in the direction of the arrows;

Fig. 3 is a top plan view of the nozzle assembly Aand its connections;

Fig. 4 is a side view of the nozzle assembly from the same point of view as Fig. 2;

Fig. 5V is a detail view, partly in section, of the nozzle operating handle and connections; and

Fig. 6 is a front view of the nozzle assembly from the same point of view as Fig. 1.

In Figs. 1 and 2 I have shown an ash hopper 1 having a bottom ormed'in sections of which the sections 2, whichV form a baiie wall orwalls, extend downwardly from intermediate'the side walls but stop short of the latter, and of which the sections3,the bottom walls proper, are walls extending downwardly from the side walls ybelow sections 2 toward each otherbut with their adjacent ends spaced apart from each other. A gridY or sizing screen 4L is'positioned between the adjacent or lower ends of the walls 3 `so that ash washed off the walls 3 may pass therethrough to a sluiceway 7 The walls 2 and 3 are so disposed as; to retain ash thereon. Means for removing accumulated ash trom the walls 2 is Yshown at 5 which indi- Cates a water line extending through the walls of the hopper to direct -streams of water against the ash on the walls'2 vto wash it therefrom. One embodiment of `means' for removing ash from the walls 3 is shown in detail in Figs. 3 to 6 inclusive.Y j

This embodiment of my invention consists of a plurality of water pipes 6 which eXtend son through aV wall 17 which, in the presentlin-` stance, is a part of the wall hopper 1. VThe pipes 6 Ymaybe supported as by brackets 81 beneath the walls 2 and each pipe Gais in communication with a depending pipe 9 having a pivotal or swingable connectionV 10.

. Each pipe y9 is preferably provided with'a nozzle 11 at its lower end, the two nozzles 11 extending in opposite directions and suitably disposed. so' as to direct streams of water against ash lon both walls 3 andvapproximately parallel to the top surfaces thereof. l

vPipes v91` are joined together to .move in unison by a plurality of clips 12. An operating handle ,or rod 13 is connected to the:

pipes 9as by; being attach-ed to a clip 12, the

rod@` 13 extendingthrough wall 17 and a cylindrical memberV 14 rotatably mounted'in. l a suitable socket 15 on the wall. Thelmembersv 14 and 15 serve toguide the rod 13 when the latter i-s beingactuated to swing-v the pipes 9 tothe positionsshown in Figs. 2 and 5. and direct streams of water progresfsively against the confronting surfaces. ot ash retained on the walls 3. Y

- It vwill be understoodv that each` pipe 6 is preferably providedwithga set otvalves and that the pipes 6 may be connected toa single source of water under:l pressure or tof/two f sourcesV as may` bel desired. Y

When ash is togbe removedrom walls".

water under pressure is admitted into pipes 6 and discharged through nozzles 1l against the ash on these walls. The rod 13 serves as a convenient single control means for swinging both pipes 9 back and forth to direct the water from nozzles ll against various parts of the surfaces of ash on the Walls 3 so that the ash is washed from these walls progressively in amounts which can be ready sluiceway 7 Jfrom nozzle 16.

Many other structures embodying my invention'will doubtless occur to those skilled -1 in the art so that I do not wish to be understood Yas limiting my invention to the details herein shown. The scope of my vinvention is defined in what is claimed.

That is claimed is: j i

1. Ash disposal means including walls spaced apart from each other for retaining ash, apparatus comprising in combination a sluiceway disposed in position to receive ash removed from the walls, a nozzle assembly including a plurality oi' pivotally suspended pipes having'nozzles disposed between and above theltops of the said walls, means connecting said pipes together for conjoint movement, and guidedl means joined .to the said pipes for swinging said pipes in unison about their .pivots to direct water progressively,againstthe ash on both walls. 1 y

2. Ash disposal means including walls spaced apart from each other for retaining ash, apparatus comprising in combination a sluiceway disposed in position to receive ash removed fromY the walls, a nozzle assembly including a Vplurality of pivotally suspended pipes having nozzles disposed between and above the tops of the said walls, means connecting said pipes together for conjoint movement, guided means joined to the said pipes for swinging said pipes in unison about their pivots to direct water progressively against the ash on both walls, vand means for supplying water-to said pipes.

3. Ash handling apparatus comprising angularly disposed walls,'a plurality Vof spaced apart walls on which ash mayv accumulate, means depending from said` rst named walls adapted to wash ash from said spaced walls, said means including a pipe,

for each of said spaced apart walls and provided with swingable connections and a nozzle positioned to direct a stream of water against ash on Vits respective wall and sub-- stantially parallel to the top thereof," the said pipes being joined ytogether to swing in unison,"and a guided rod connectiontol the pipes for swinging the pipes in unison.

4. Ash handling apparatus comprising a hopper having angularly disposed Vbaille walls and spaced bottom walls on whichash may accumulate, means depending Jirom said iirst named walls adapted to wash ash from' said spaced bottom walls, said means including a plurality of pivotally depending pipes, discharge nozzles oppositely and angularly disposed on the lower ends of said pipes and means, operable from outside of the saidhopper, `for swinging said pipes to oscillate said nozzles.

5. Material handling apparatus including a hopper having bottom walls arranged to provide a hopperA discharge opening, a bai- -fle wall overlying said discharge opening and spacedV above said bottom wall, means disposed below said baiile wall adapted for washing material from said bottom wall, said means including pivotally suspended pipes having nozzles'positioned to direct streams lof liquid against material onsaid bottom wall, said pipes being disposedbeneath said baffle wall and joined together to swing in unison, means, operable from outside of said'hopper, for swinging said pipes about their pivots, and means for supplying liquid to said pipes.

G. Material handling apparatus comprising a hopper having angularly disposed baiile walls, spaced bottom walls disposed below said baiie walls and adapted to receive material from said baffle walls, means disposed below said baille walls for washing material from said spaced bottom walls, said means including a pipe for each of said spaced Vbottom walls and provided with swingable connections and a nozzle positioned to direct a stream' oi` liquid against material on each respective bottom wall portion and substantially parallel to the top surface thereof, the said pipesbeing joined together to swing-in unison, and a guided 105 rod connection to the pipes for swinging the pipes in unison.
